PUSH BUTTON HOUSING Filed Feb. 17, 1928 INVENTOR ATTORNEY Patented Mar.11, 1930 UNITED STATES PATENT OFFICE NEIL G. HAYES, OF BRIDGEPORT,CONNECTICUT, ASSIGNOR OF ONE-HALF T ADEL- BERT R. AURAY, OF BRIDGEPORT,CONNECTICUT' FUSE-BUTTON HOUSING Application filed February 17, 1928.

This invention relates to electrical push button constructions, andparticularly to the housing enclosing the electrical mechanism, itsobject being to form the housing and all parts thereof for supportingthe button and electrical mechanism of a single piece of sheet metal,thus reducing the number of parts and materially cheapening the cost ofconstruction.

Referring to the accompanying drawing wherein the same characters ofreference indicate like parts throughout the several views- Figure 1represents an elevation of the housing and its push button- Figure 2 isa central sectional elevation of an integrally constructed housing-Figure 3 is a broken view of the exterior part of the one piece housingand a full view of a depending interior portion--u Figure 4 is aninterior plan view of the housing- Figure 5 is a bottom plan view of thehousing equipped with the electrical mechamsm- Figure 6 is a sectionalview of the housing and a full view of the electrical mechanism, and

Figure 7 is an enlarged broken sectional View of the housing and itsintegrally depending features.

The one piece sheet metal housing consists of the shell l having theinwardly projecting flange 2 and the opening 3 through which projectsthe body 4 of the push button, while the fiange 5 of the button isnormally held against the underside of the Harige 2 by the conventionalcontact springs 6.

The depending shell 7 embraces the button and the major part of theelectrical mechanism with the base 8 resting against the end of theshell 7, and is held there by the integrally projecting clips 9, theconventional electrodes 8a being secured to the base 8. The dependingmember 7 thus forms a supporting housing for the electrical mechanism.The member 7 is first drawn down from the central part of the shell l oftubular form and its sides upset to form an inwardly projecting fold forthe push button support 2, as shown in Fig. 7.

Serial No. 254,944.

The prevailing type of push button housing constructions carrying thenecessary electrical equipment, are made of sheet metal, and comprise aplurality of assembled parts to support said equipment, thusmateriallyvincreasing the cost of production.

In the present improvement, a single piece of sheet metal is shaped, byproper tools, not shown, to form the outer shell l, and the internalsupport for the electrical equipment, thus making a neat, compact, andcheap construction to which the electrical mechanism is readilyattached.

Certain type of push button constructions are sunk below the surface,but the type herein shown contains the electrical equipment and aresupported on the surface and project above the same.

The gist of the invention resides in a push button housing, having acentral push button opening, a retaining support for the button with asupport for the electrical mechanism depending therefrom, all made of asingle piece of sheet metal.

lVhile modified changes could be made as to the general shape of the onepiece housing construction, any such changes that includes a retainingsupport for the button and a support depending therefrom for electricalmechanism, must necessarily be considered the equivalent of myconstruction,

Having thus described my invention what I claim is :Hw

A push button construction formed from a single piece of sheet metal,comprising an outer shell having a central and inwardly dependingtubular portion, said tubular portion being adapted to embrace andsupport the electrical mechanism, and an inwardly projecting push buttonsupport formed by folding and upsetting the metal of said tubularportion.

In testimony whereof I affix my signature.

NEIL G. HAYES.
